Furthermore, with the continuous innovation of architectural design and construction technology, the application of new materials will become more diverse and personalized. As awareness of building fire prevention continues to grow, people are also placing a series of safety requirements on building materials. To ensure that building materials meet standards, individual combustion tests are often conducted to verify their compliance with relevant standards. When building materials catch fire, smoke production can affect the survival of occupants and the time it takes for outsiders to respond. Therefore, individual combustion test devices for building materials are often used to inspect building materials. However, existing individual combustion test devices for building materials typically target specific locations on the building material, resulting in incomplete combustion. This phenomenon can easily lead to inaccurate smoke generation rate and composition detection results during smoke detection. Therefore, there is a need to develop an individual combustion test device for building materials that can promote complete combustion of building materials and ensure accurate test results.

Place the building material product in the clamping groove formed between fixed plate 601 and movable plate 602. Under the elastic force of spring 606, push movable plate 602 back to clamp the building material product. Once the clamping is stable, close the chamber door. Then, control telescopic rod 4 to drive burner 2 downward to the bottom of the building material product. Open the valve on gas cylinder 15, start burner 2, and combustible gas will be ejected from nozzle 201, burning the building material product in all directions. During the combustion process, control telescopic rod 4 to drive burner 2 upward to burn the building material product, ensuring that the building material product is fully burned. The smoke generated by combustion enters the exhaust pipe 8 from the gas collecting hood 5, and the smoke detector 19 is started to detect the smoke generated by combustion, and detect parameters such as smoke concentration and smoke generation rate; water is added to the purification box 9 through the water inlet in advance, and the water submerges the lower end of the exhaust pipe 8, and the induced draft fan 10 is started synchronously. The smoke enters the purification box 9 along the exhaust pipe 8, and the water can remove most of the particulate matter. Then, under the action of the induced draft fan 10, it passes through the filter cotton 13 and the activated carbon layer 14 for filtration and adsorption, and then is discharged. The substances generated by combustion fall into the collection box 7. After the collection box 7 is full, open the box door and take out the collection box 7 for cleaning. When the equipment needs to be moved as a whole, it can be moved using the moving wheels 18. When the water in the purification box 9 needs to be replaced, open the valve on the drain pipe 11, discharge the sewage, and refill it with water from the water inlet.
